Community Fault Model

August 12-13, 2025
University of Oregon Portland Campus, Portland, OR

Workshop Goals

Workshop Description

We are convening a workshop to solicit input from the community on the CRESCENT Community Fault Model (CFM) v1.0 and discuss improvements for future versions of the CFM. The workshop will highlight the current goals, criteria for inclusion, and status of the CFM. We welcome participants to share new results from both previously known and newly discovered fault systems in both onshore and offshore regions of Cascadia. The workshop will focus on faults in both the upper plate (North America), the lower plate (Juan de Fuca), and the plate interface.

We seek input from workshop participants about how to improve and augment the representation of faults and other structures through focused, regional-scale discussions. We look to solicit feedback from a variety of community members, including from federal, state, and local agencies, from academic institutions, and from utility, consulting, and other private industries. These conversations may highlight where future fault investigations are needed. We hope to gain a better understanding of the community needs, uses, and other considerations as we plan for the next update of the CFM.

Goals:

  • Communicate current status of CFM, including criteria for inclusion, faults included in CFM v1.0, and how faults are meshed and represented in 3D.
  • Describe working model and planned updates to CFM, highlighting offshore faults. 
  • Solicit feedback about current faults included in the CFM and new faults (with data) that can be considered for inclusion and meshing. 
  • Understand additional uses, specific needs, and expectations from the community for the CFM.
